Here is the problem. I have a text file of a log and some of the output looks like this

some text
======
description

and some looks like this

some text
======
blank line

Is it possible to delete "some text" and "======" only if the next line is blank?

I found the sed one-liners page and the use of sed only is for a single line it looks like.

Or is there a better program to use?

Thanks for any help...
